The software is written in assembler, as it is very short and it need the speed in the main loop.
This is the heart of the synth. To be precise, it s in the 7 lines of assembler that makes up the main loop.
The rest of the code is the wavetables and the communication code.

Digital Signal and Image Processing Using MATLAB
The most important theoretical aspects of image and signal processing (ISP) for both deterministic and random signals are covered in this guide to using MATLAB&#174 . The discussion is also supported by exercises and computer simulations relating to r ...
书籍 Goldbort_Writing for Science
Although doing science is at the heart of discovery, the effort would have
very limited consequence in the long term without writingscience. As a social
enterprise that depends on collaboration, scientific inquiry requires its practi-
tioners to write on a regular basis. From time to time, some memb ...
